Transport in Europe is responsible for damaging levels of air pollutants and a quarter of EU greenhouse gas emissions. Many of the resulting environmental problems can be addressed by stepping up efforts to meet new EU targets, according to the latest report from the European Environment Agency (EEA).

Real-time data from around several thousand air quality measurement stations across Europe are transmitted to the EEA in Copenhagen on an hourly basis. Since the data must be as 'real-time' as possible, the data are displayed as soon as practical after the end of each hour.

The global population is congregating in our cities. Eighty per cent of the world’s estimated nine billion people in 2050 are expected to live in urban areas. Our cities and urban areas face many challenges from social to health to environmental. The impacts of cities and urban areas are felt in other regions which supply cities with food, water and energy and absorb pollution and waste. However, the proximity of people, businesses and services associated with the very word ‘city’ means that there are also huge opportunities. Indeed, well designed, well managed urban settings offer a key opportunity for sustainable living.
